A new marketing tool: Life-cycle costing

Life-cycle costing is a method of calculating the total cost of ownership over the life span of the industrial product. It can be especially useful in the marketing of industrial products that sell for high initial prices, but which provide long-run cost savings. This paper explains the life-cycle concept and its implementation.     

Contract costing in outsourcing enterprises: Exploring the benefits of discrete-event simulation

Outsourcing is a business strategy that has received much attention. An increase in outsourcing has a direct influence on the complexity of supply chain networks and on the number of contracts required to manage a supply chain. Outsourcing contracts may be entered into relatively quickly without a full understanding of the true cost implications. The research described here aims to develop tools based on discrete-event simulation to aid outsourcing companies when costing contracts. Currently available software for this type of application is reviewed. A field study is presented from the electronics sector, describing companies’ needs with respect to contract costing and how simulation could be used in the contract costing process. Simulation approaches are described for different contract costing scenarios. The paper concludes with a case study of a preliminary simulation model that has been developed to test the concept with a specific outsourcing scenario.     

Applying activity-based costing in a supply chain environment

Traditional intra-firm cost accounting tools are not appropriate in the context of supply chain management, as there are no standards for the definition and composition of costs. This prohibits exchange and comparison of cost data among different supply chain members. Against this background, several activity-based costing models for inter-firm cost accounting have been proposed. Evaluating these models, a conceptual framework for activity-based costing in a supply chain has been developed. This also forms the basis for a single case study conducted at Europe's largest company for façade components. This demonstrates how significant inter-firm cost saving opportunities can be identified and offers a first step in assessing the suitability of the proposed model.     

Optimal replenishment policy for a deteriorating green product: Life cycle costing analysis

In the last few decades, enterprises are trying to recycle the used products to reduce the negative impact on environment. This results in the need for reverse supply chain model especially for deteriorating items. The proposed model considers vendor managed inventory strategy and conducts a life cycle cost and benefit analysis for green electronic products. The mathematical analytical approach is used to solve the proposed model. The results show that selling price, deteriorating rate, holding cost, product return rate, and remanufactured quality have a significant effect on the model. This study can provide managerial insights into improving the design of a green-supply chain.     

Time-driven activity-based costing for health care provider supply chains

ABSTRACT

Health care providers currently operate in an environment of complex supply chains and increasing costs where approximately one third of hospital operating expenses are related to supplies. It is pertinent that health care providers have a clear understanding of their supply chain process costs. Knowing how these costs are driven and where opportunities for cost reduction exist can support health care provider supply chain (HPSC) efficiency. In this article, we present a time-driven activity-based costing (TDABC) supply chain cost methodology for health care providers. A TDABC management system can provide health care providers with valuable product and process supply chain cost information by investigating logistics activities, resource consumption, and time drivers. Our HPSC TDABC methodology is demonstrated in a case study conducted for the supply chain department of a 200-bed, not-for-profit hospital.     

Quantifying the effects of product family decisions on material selection: A process-based costing approach

Product designers must continually assess trade-offs among various performance attributes and cost. Materials choice can play an important role in that decision-making process. Product platforms are used to meet the demand for increased product variety, while also managing costs. Because of their interdependent effects, it is possible that platforming strategies may alter preferred material choice. This paper examines the interrelationship of these early stage design choices through the application of process-based cost modeling.A case study is detailed concerning two alternative material options for an automotive instrument panel beam: a die-cast magnesium design and a conventional design (i.e., discrete stamped steel components) which allows for more component sharing than the integrated magnesium design. The effects of component sharing on product family costs are analyzed. It is shown that the magnesium design is less competitive in platformed scenarios.

Simulation-based costing for early phase life cycle cost analysis: Example application to an environmental remediation project

Simulation-based costing (SBC) has been slow to be adopted by the traditional cost estimating community. This can be attributed to many factors, including complexity, how to gather data and develop probabilistic inputs, cost of SBC software, and a lack of understanding of the benefits of developing cost versus risk profiles. This article presents an overview of how SBC can be effectively utilized for early phase life cycle cost (LCC) estimation. A formal process for conducting LCC incorporating SBC is presented not only to provide a structured approach but to also convey to stakeholders how such a study is conducted. This article also presents a case study where total ownership cost versus risk profiles were developed using this proposed process in order to support budgetary and planning considerations for a large environmental remediation project. This research argues that SBC is needed during the concept exploration phase because this is when budgets are often fixed and expectations set.     

A comparative study of the adoption and implementation of target costing in the UK, Australia and New Zealand

Most of the studies on target costing (TC) only provide insight into the adoption and perceived benefits of TC, and do not address the levels of implementation of the technique. These studies also assume that TC is only relevant to manufacturing firms and therefore do not investigate the adoption of this technique in service firms, and consequently exclude service firms from their surveys and analysis. Furthermore, most studies do not examine factors influencing the adoption of TC systems. Contributing to these gaps in the literature, this paper reports the results of a survey among CIMA-qualified management accountants working in manufacturing and service firms in the UK, Australia and New Zealand on the adoption and implementation of TC. The study examines the importance of attributes of TC (namely relative advantage, compatibility, ease of use, result demonstrability, trialability) for decision makers to adopt and implement such cost and management accounting innovation. The survey indicates that TC is equally prevalent among manufacturing and service firms while in terms of the levels of implementation there is a significant difference between manufacturing and service firms. The study shows that there is a growing interest in the examination of all cost-reducing strategies at the planning stage and adoption of value engineering to incorporate customer requirements rather than focusing on the adoption of cost-cutting strategies at the production stage.     

Application of discrete event simulation to the activity based costing of manufacturing systems

In the last two decades traditional cost accounting practices have been unable to respond to the changing information needs of manufacturing management. Activity Based Costing (ABC) is a method which can solve many of the limitations of traditional cost systems. This method of accounting involves the breaking down of the individual activities and costing of the amount of time spent on each step of the manufacture of a product. This paper illustrates how Discrete Event Simulation may be used to evaluate the ABC of a manufacturing system. A visual interactive simulation software WITNESS is used to model a semi-automated Printed Circuit Board (PCB) assembly line. The PCB assembly line case study demonstrates how ABC can be applied to a manufacturing system using simulation modelling techniques. The paper also discusses further applications of ABC in the manufacturing environment and includes a case study on the operational quality cost.     

A comparative analysis of utilizing activity-based costing and the theory of constraints for making product-mix decisions

Activity-based costing (ABC) and the theory of constraints (TOC) represent alternative paradigms for evaluating the economic consequences of production-related decisions. However, their application can lead to contradictory product-mix decisions. To resolve this conflict, it is frequently suggested that the TOC is appropriate for the short run, while ABC is appropriate for the longer term. This paper models the selection of a product mix with the TOC and an ABC model integrating activity-based cost with the capacity of production-related activities. The paper demonstrates that management's discretionary power over labor and overhead resources determines when the TOC and ABC lead to optimal product-mix decision. Equally important, it demonstrates that both the TOC and ABC may lead to a suboptimal product mix across a wide range of economic conditions. The paper develops a more general model of the product-mix decision and demonstrates that the TOC and ABC are special cases of this model. Finally, the paper discusses how the general model may be used to supplement information provided by the TOC and ABC.     

A comparison of product costing practices in discrete-part and assembly manufacturing and continuous production process manufacturing

Research into product costing practice has not studied whether there are differences in product costing practice between different types of manufacturing. This paper compares the product costing practices of operating units in discrete-part and assembly manufacturing, and continuous production process manufacturing. The results show that there are few differences in product costing practices between these two manufacturing methods. Similar proportions of operating units in these two manufacturing environments use similar methods to treat overheads and have similar experiences of activity-based costing. The only area of difference is in the use of overhead rates where significantly more units in discrete-part and assembly manufacturing use a direct labour hour rate and significantly more units in continuous production process manufacturing use units produced and production time-based rates.
